Beit known'that'l, Lnoromi DiLfiTii-, a citizen olf'theUnit-edStetes;residing' aftNeur` York, in the county oft New York" andi State of NewYork", have" invented certain new' andE useful Improvements in Tobacco'Pipes; of `which the following is a'. speciiicati'on.

`This 4invention"relates :generally to 'tobacco pipes; andIiiore'p'articularly to an' improved construction of iiiouthpie'ce to'be used in connection with" pipes in which the bit; is made detachablefrorhjthebowl meaiisiof a; push 'that entersulelstmep Off u1@ boei to'connect www@ parte of the pipe" rigidly' together,` In order to'lprevent: breakage such' as frequently results i'ifoin the'y tapping orknocking of the'pipe againetY a. hard suiitace to dislodge ash and otherresiduey from the bov'vfl, it hasfbeen common practice to inake'thepushwof' a' material like aluminum for" 'inst-ance, which maybe moldedEin the endi of thiebit" or mouthp"ieee,` thereby strengthening the bitat its connection with thelstunip 'of thebowlf `While the bit thusprovided With a moldeldlin push or connection is undoubtedly, strongerthen a mouthpiece 'ma'dethroughout of hardrubber for instance", withanlintegr'al reduee'dend o'r teno'ni, it' issometimes found A inpractice that While the aluminum push or' tenoii htsvery WellWhenfthefpipeis newvthe'fit is' apt' tobecome loose" whenthevoodshriiiks a'iterV a'` period of use. Sofa-rv as the itbetveen'tenon and'b'owl islcon'cerned; theha'rd rubber bit with integraltenon gives veify satisfactoryiresults, because the hard rubber appearsto, have moreresili'ence and possibly expands slightly as theWoodinto"WhichitE is inserted shrinks.' 7

Thebitfis'molde'd around"the" connection' piece 7`- and around -in'g part` of tlief pieceAv 7".And the'l spiral groeve denied ,by uis' thread! s* in the: pr@- jenne'pue @fue piece? refine-ewan nieni sittin or theiba,fni-iuistrai1ec; heremitbug sub-Seminar upw the' ivu: of the Y threadand; so" tliat'there inthis" roove integral?v reduced eitension of t ef bit combinationsv l1 ofthe thread. Thus, there is provided a` circumferential shoulder 12.

From the construction described it will be Aevident that there isprovided a tenon hvavingian exterior surface for lfrictional en- Igagementwith the walls of the stump, which surfaceis in part metallicand in part hard rubber. The connection between the mouthpiece and thebowl is reinforced to the extent that the piece 7 is stronger than themouthpiece proper, and the connection piece is solidly anchored in themouthpiece. The tenon possesses the advantage that itl is easilyinserted into andV removed from its seat, both by reason ofv themetallic surfaces which are'eXposed, and because of the screw actionwhich ispossible. At the vsame time, because of the partial hard rubbersurface of vthe tenon, continued tightness of iit is guaranteed. rAt thesame time the advantages of al-uminum (non-corrosiveness, cooling of thesmoke, etc.) are retained.

It is evident that by regulating the pitch of the thread 8, or the widththereof, at least -as'to that part ofthe piece 7 which constitutes theconnection, the relative proporytions of metallic and hard rubbersurfaces exposed in the tenon can be controlled, ac-

cording to need. The article is found to give entire satisfaction inusefrom` the utilitarian standpoint, and is entirely distinctive andattractive in appearance.

It is within kthe purview of the invention to make the connecting pieceseparable from lthe bit proper. In that case, the piece will not bemolded in with the mouthpiece, but the threads .at one end thereof (theright-hand end in Figure 3) will be yscrewed 'into'the correspondinglythreaded end of the bit, and of material, such as the hard rubber of thebit, will be molded in position 'between the spirals of the thread atthe lefthand end of the piece, that is, the end which will constitutethe pushi when the parts are assembled. lith this arrangement themouthpiece would perhaps be not so strongly reinforced, but there wouldbethe' ad :vantage of replaceability of the connection piece if the fitbetween the tenon and the bowlshould become loose.

Itwill be understood that while I have in this specification referredspecifically to4 hard rubber, aluminum, and other materials, I intend nolimitations whatever to particular materials. The essentials of theinvention are in the provision of a reinforcing 'connection piece whoseouter end constitutes the tenon of the bit, and which outer end maarreis provided with certain portions which have greater frictional and orelastic qualities than other portions. In another aspect, the inventionincludes a bit of hard rubber or the like, with a reinforcing connectionpiece molded therein and constituting a tenon, this reinforcing piecebeing of stronger material than that of the bit itself and the tenonpresenting distinct surfaces which are integralrespectively with thematerial of the bitand the material of the connection piece.

Inasmuch asmany changes AcouldlbeV made in the above construction, andmany apparently widely different embodiments of my invention could bemade without departing from the-scope` thereof, it is intended that allmatter contained in the above description or rshown in the accompanyingdrawings shall be interpret-ed as illustrated and not in a limitingsense.

It is also to be understoodthatthe lan-Vv guage used in the followingclaims isintended to cover all the generic and speci'iic features of theinvention hereinvdescribed and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween,

Abit having a tenon endvcomprising an internal tubular reinforce made ofV inaterial dierentfrom the'material of the bit proper, and a member integral andcontinuous .with and. of thersame material as the bit proper, overlyingthe tubular reinforce, a portion of the outer wall of the reinforceextending through the said meniber flush with the outer surface of thelatof the bitproper, anda Afriction niemben integral with the bit andoverlying the reinforcing member, the reinforcing member and thefriction member in their assembled relation having flushexterior wallportions.

e. The device described in claim 3 Lin which the connecting piece is ofgenerally tubular form, with aplurality of portions projecting above theouter surface thereof, and in which there are portions integral with thebit itself positioned upon the eX- terior of the connection piece andbetween said projecting portions of the connecting piece.
